Two‐way relay networks based on product relay

Abstract

Two‐way relay networks in additive white Gaussian noise channels are studied. A novel scheme based on the product relay is proposed and the whole block diagram is obtained. Furthermore, the presented analysis shows that the proposed scheme outperforms the traditional amplify‐and‐forward relay. Two‐way relay networks based on the product relay provide a better bit error ratio performance in high signal‐to‐noise ratio regions, which is consistent with the simulation result.
